DIE-"SUPPORTING BLOCK AND SW-AGER.

Specification ofLjetters Patent.

Patented April 27', 1909.

Application riled July 81, 1907. Serial No. 386,410.

.To all whom it may concern: I

lie it knownthat I, .WILLIAM TfLYoN, re-

siding at Portland, in the county of Mult nomah and State. of Oregon,have invented certain new and useful Improvements in Die-SupportingBlocks and Swagers, of-

which t e following is a specification.

My'invention relates to certain new and useful improvements in'swagers,and par ticularly seeks to rovide an improved swager adapted to lie usedin connection with the improved type of dental appliance disclosed in myco-pending application filed on even date herewith, Serial No. 386,409,and in its generic nature, the invention embodies an improved form ofswaging mechanism hereinafter more fully described. In its more detailnature, the invention comprises certain novel details of construction,combination and arrangement of parts, all of which will be first fullydescribed, then s ecifically ointed out in the appended claims, and ilustrated in the accompanying drawings, in which Figure 1, is aperspective view of the swager forming a part of my invention.

Fig. 2, is a similar view showing the parts thereof separated. Fig. 3,is a detail per spective view showing the manner of placing t eimpression in position on the die supporting block and filling aroundthe outer edge with a plastic material to prevent escape of moltenmetal. Fig. 4, is a similar View showing the method of casting the dieby pouring the fusible metal into the heel of the im ression. Fig. 5, isa perspective viewthe die supporting block and die. Fig. 6, isaninverted perspective view of the die removed from the casting block.Fig. .7,- r

is a central, vertical longitudinal section of the device hereinafterspecifically referred to.

Referring now to the accompanying drawings, in which likeletters' andnumerals of reference indicate like parts in allof the figures, 1designates the swager which is formed in three parts, consisting of thedie supporting block 2, the ring" 3Qand the follower 4, as shown in Fig.2 of the drawings, by reference to which it will be seen that the die fsupporting block 2 has its upper face 2 pro The ring 3 fits snugly overthe die supporting block 2, in practice, and the follower 4 fits withinthe ring 3, over thebloel; 2. Any improved means of holding the threeparts of the swager together when in the position shown in Fig. 1, mayhe provided, as such means, per so, forms no part of my presentinvention; such holding means may be that shown in my co-pendingapplication hercinbefore referred to, or the three sections may beclamped together in any approved manner.

In the practical application of my invention, the impression of themouth is taken with plaster of paris on an impression tray, asin anyordinary operation, and after the excess of plaster is trimmed oh, thetray may be reversed and the plaster of paris impression held flatwiseon the die supporting block over the depression 2 as shown in Fig. 3 ofthe drawing. After the impression has been placed against the diesupporting block directly over the de ression therein, (see Fig. 3) theoperator fil s around the outer edge of the impression with moldine orplaster 6, to prevent the escape of the molten metal which is to beouredinto the impression, as hereinafter escribed.

The block 2 with the laster impression is thoroughly heated by p acingthe same over a slow flame to prevent the metal from chilling tooquickly, since the fine lines of the mouth are brought out much better,if this is done. After the die su porting block has been warmed, asstated, th poured into the impression through the heel thereof, as shownin Fig. 4. As soon as the metal has become sufiiciently cooled to becomeset the plaster impression is removed from the block leaving the metaldie in position on the face of the die supporting block, ready for thenext operation, it being understood that the molten metal has run intothe depression 2 and become interlocked therewith. The metal plate 7 maythen be placed over the die in the usual manner, after which, the ring 3is laced over .the'die supporting block, and a .exible diaphragm 8 maybe placed over the metal plate 7, and the die, and the plastic material9 filled into the ring after which the follower 4 is pressed down intothe ring to compress the plastic material therein, the follower 4 havinga central aperture 4 to permit the insertion of a swaging plunger 10which may be operated in any approved manner,

e molten metal is' either by hammer-in thereon, or by the use of themachine disc osed in my co-pending application hereinbefore referred to.The

parts are then in the position shown in Fig.

7, the block 2 may be removed from the ring 3 and the swaged plateremoved from the die very readily. The die may be also removed from theblock 2 by sliding it out of the depression 2 from the back toward thefront thereof.

By constructing a swager having a casting block, as shown and described,the die may be readily removed from the block and other dies substitutedor formed thereon without in any manner destroying the die so as toprevent its future use, whenever desired. This is a very great advantageof my invention and enables the dies to be re-used, a thing that isimpossible with the ordinary type of die supporting block now in commonuse.

From the foregoing descriptiontaken in connection with the accompanyingdrawings, it is thought the complete construction, operation, advantagesand use of my invention will be readily understood by those skilled inthe art to which the invention ap pertains.

hat I claim is 1. In a swager, a die supporting block having awedge-shaped depression in one face to receive a portion of the die toremovably retain the same, the bottom surface of the depressed portionsloping from the bottom of the depression at one end to the top thereofat the other end, substantially as shown and 1 described.

2. In a swager, a die supporting block having a de )ression in one faceto receive a portion of tie die to removably retain the (lie, the bottomsurface of the depressed portion commencing at the top of the block atone end of the de ression and extending downwardly towar the other end,said blocl; having an undercut portion at such other end, substantiallyas shown and described.
